Ecumaster forum

first one to use this ecu with my local tuning shop, ecu took some time to figure out but car made 603whp so im happy. however with drag season coming up im trying to get my launch control set up. i set it to (always on) and the vss to 3mph, however with it always on the car will still hit the 4k limiter past the set 3mph. What am i missing here, is it a setting or maybe my speed sensor is faulty.

Thanks!

this is what i have used in the past and was ok , lc stops fine for me with the vss . i need to double check fueling on this one myself again before i use it in anger again .

do you have a log file ?
